So we're pretty psyched that OPI has announced a huge Facebook giveaway where winners have the chance to score a set of six retired nail lacquer shades, including Kinky in Helsinki, Smokin in Havana, Hoodoo Voodoo, Parlez-Vous OPI, Sahara Sapphire, and Cheyenne Pepper.

If the nail brand reaches its goal of 100,000 "Likes" on its Facebook page by December 31, OPI will open the vault of retired shades for 100 lucky winners.

And for every friend you refer who enters the giveaway, you receive an extra entry to help increase your chances of winning.
